System disturbance
Some conditions can disturb or damage the system's operation, such as:
– a complex environment (metal bridge, tunnel, etc.);
– poor weather conditions (snow, hail, black ice, etc.);
– poor visibility (night, fog, etc.);
– poorcontrastbetweentheobject(vehicle,pedestrianetc.)andthesurroundingarea(e.g.pedestriandressedinwhitelo-
cated in a snowy area etc.);
– being dazzled (glaring sun, lights of vehicles travelling in the opposite direction; etc.);
– windscreen obscured (by dirt, ice, snow, condensation etc.);
– ...
In these conditions, the system may not react, may warn the driver or may brake inadvertently.
Limitation of the system operation
– Eachtimethevehicleisstarted,thesystemcarriesoutacalibrationaccordingtothevehiclesurroundingsandmaybein-
active for approximately two to five minutes;
– The radar and camera areas must be kept clean and free of any modifications to ensure the proper functioning of the
system if the conditions described in the "Special cases of oncoming vehicles when changing direction" are met;
– the system may not respond to small vehicles such as motorbikes as effectively as to other vehicles;
– the system may not operate properly when the road surface is slippery (rain, snow, black ice, etc.);
– to ensure correct operation, the system needs to distinguish the complete outline of the pedestrian. So the system cannot
detect:
– pedestrians in the darkness or in poor lighting conditions;
– partially visible pedestrians;
– pedestrians less than approximately 80 cm;
– pedestrians carrying large objects;
– ...
In these conditions, the system may not react, may warn the driver or may brake inadvertently.
